.
EVENT...STORM CONTINUES TO DEVELOP OFF MD-DE COAST...BEST DEFORMATION
BAND COOLING CLOUDS NOTED JUST OFFSHORE LONG ISLAND FROM THE RHODE ISLAND
COAST TO CAPE AND ISLANDS...
.
SATELLITE ANALYSIS AND TRENDS...BEST LOOKING SHORT WAVE LIFTING NORTHEAST
JUST OFF THE NORTHEAST NC/SE VA COAST AND HELPING RO CONTINUE TO DEVELOP
SURFACE LOW OUT AHEAD THAT WAS CENTERED BASED ON PREVIOUS MICROWAVE AND
ASCAT WINDS AND CURRENT SHIP AND LAND BASED OBSERVATIONS JUST OFF THE
MARYLAND/S DELAWARE COAST.    SATELLITE UPPER LEVEL WIND TRACERS SHOWING
QUITE WIDE AREA OF WEAK UPPER LEVEL DIFFLUENCE MOSTLY TO THE NORTH AND
NE OF THE SURFACE LOW.  JETLET OR MINI JET STILL WELL DEFINED ALONG THE
COAST FROM THE DELMARVA TO LONG ISLAND  TO DOWNEAST  MAINE AND HELPING
REJUVENATE  DEFORMATION BAND JUST SOUTH OF LONG ISLAND.  DEFORMATIO BANDS
BETTER RECOGNIZED JUST SE OF LONG ISLAND AND PEELING ENE TOWARD THE SE MA
ISLANDS AND THE CAPE FOR INCREASED  INITIAL SNOW BURSTS THERE SIMILAR TO
WHAT NYC WAS EXPERIENCING EARLIER THIS AFTERNOON.    MAX DIVERGENCE ALOFT
BULLSEYE WELL SOUTH OF SE NEW ENGLAND BUT  RELATIVIE MAX DID EXTEND NORTH
INTO CT AND RI.    MOISTURE PLUME IN THE WESTERN ATLANTIC CONTINUED TO
ORGANIZE WITH  SWLY MOIST ADVECTION FROM CUBA AND THE WESTERN CARIBBEAN
COMBINING WITH MOIST BAND OF FRONT THAT HAS COME OFF THE SOUTHEAST US
AND OLD FRONTAL MOISTURE NEAR 30N/66W THAT WAS LIFTING SLOWLY NORTH.
SO MOIST INGREDIENTS COMING TOGETHER...BUT STILL STAYING FAR ENOUGH
OFFSHORE SO THAT THE 0.5" PWAT VALUES DON`T GET TOO CLOSE TO THE COAST.
GRADIENT OF PRECIPITABLE WATER CONTINUED MODERATE FROM NE NY-CENTRAL NEW
ENGLAND SOUTH TO OFFSHORE LI AND THE MA CAPE/ISLANDS..WHICH CONTINUES
TO MAKE FOR A GOOD POTENTIAL OF MOISTURE ADVECTION/TRANSPORT INTO SE NY
AND SOUTHERN NEW ENGLAND.    LATEST MICROWAVE ACCUMULATIONS OF PRECIP FOR
THE 6HR PERIOD ENDING 00Z SHOWED A MAX OF 0.75"-1.0" CENTERED 37N/ AT 69
TO 70W WITH SOME SPOTTY AMOUNTS UP TO 0.50" AS FAR NORTH AS 39.5N (70W).
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 0015-0315Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...LOW SHOULD EASILY CONTINUE TO DEVELOP WITH
INCREASED DEEPENING AS SHORT WAVE BEGINS TO CATCH UP TO SURFACE LOW.
HEAVIEST PRECIP SHOULD BE CONFINED TO SCATTERED DEFORMATION BANDS
COASTAL LONG ISLAND..RI...S CT AND EXT SE AND E MA INCLUDING THE CAPE
AND ISLANDS BUT NOT WELL ORGANIZED AND CONCENTRATED LIKE THE ONES JUST TO
THE SOUTH AND SW THAT WERE SHOWING BETTER COOLING CLOUD TOPS IN MESOSCALE
DEFORMATION AREAS AHEAD  AND N TO NE OF THE SURFACE LOW.
